The U.K. leader, his wife Samantha and their three children Nancy, Arthur and Florence were enjoying lunch at the Plough Inn in Buckinghamshire, England with other families before leaving to return to his country residence Chequers.
However, Cameron was left horrified after realising daughter Nancy, eight, had been left behind.
The politician’s aides called the pub’s management and found that the child had been found in the venue’s bathroom safe and well.
A spokesperson for the prime minister tells The Sun, “The PM and Samantha were distraught when they realised Nancy wasn’t with them.
“Thankfully when they phoned the pub, she was there safe and well. The PM went down straight away to get her.”
